Knock..Knock

If u r scared of listening ghost story.. then u dun have to finish reading this post. I won't blame u...

I was not woke up by alarm clock but by weird sound these 2 days continuously. Yesterday, I was sleeping until 7am, I switch off the alarm and fall back to sleep..ZZZzzzz But then at 8am, I heard someone knock my room door. I woke up and wondering who is that? After knewing that there is nobody outside the door, I cannot sleep back anymore..

Then the 2nd time was this morning at 5am, I heard "knock..knock" again.. The sound is loud and clear until I jumped up from the bed. This time is 5 in the morning ler, my housemate won't knock my door at this time gua? So I was awake until 7am only I can fall back to sleep again..

Okay, so u must be thinking that might be 'someone' who knock my door, but actually this is not the first time I experience this but is the 4th times oledi. 1st times was when I was staying in Subang, 2nd time was when I was staying Damansara Heights, 3rd and 4th time were happened when I'm staying in Bandar Menjalara. So, it is definately not ghost who knock my door...

But then how come I heard "Knock..Knock"??
